Posted - 11/09/2011 : 5:28:25 PM Its great we have our own location for us HO narrow minded folks now so i thought it might be worth starting a lounge for our general discussion.
So lets get the ball rolling and see what everyone has in the works on their bench? Or tell us where and why you model in the scale. |

I've done it both ways on the four electric quarry engines I built. If you anneal the brass you need to be careful because it now bends very easy. You can get a kink it real fast. With the un-annealed brass or half-hard it's sometimes difficult to get the exact curve you want. It's a technique that takes a few tries before you get one the usable and fits the roof correctly without any gaps between the roof and side walls. Practice, practice and then more practice.

Nice looking building as always.
Dave,
Thanks, great tip on the cardboard if one uses wood. Kind of tough if one uses brass.

Posted - 03/16/2017 : 12:05:23 PM The roof is laser-cut thin plywood, that I soaked and then formed around a can. One trick was to put a piece of cardboard over top of the wood, to help get a more even bend:

Interior walls:

And a partial assembly to get an idea for the feel of the place:

Cheers, Jeff. |

Posted - 03/16/2017 : 08:51:54 AM Yes, very nice looking. I like the curvature of the roof. It's very even. Is that a solid piece milled out to fit or a thin piece of wood curved? Inquiring minds.

Posted - 03/16/2017 : 07:25:26 AM Nice progress, Dave. Aren't the handrails fragile?

Posted - 03/15/2017 : 9:09:06 PM A bit more progress on the caboose. The end handrails are laser-cut from thin laserboard. I wasn't sure about that idea, but they worked out fine.

 HOn30 is alive and well :-)

Posted - 03/15/2017 : 1:57:45 PM It's just those 1-handed clamps, and the tails are held in place with my shop vise.
Those are the cheapo clamps, I do NOT recommend buying them. They don't work anywhere near as well as the brand name (Irwin) blue and yellow 1-hand clamps.

Posted - 03/15/2017 : 12:35:21 PM Dave (Deemery) tell me more about your clamping system. |

Posted - 03/13/2017 : 5:22:52 PM Thanks Dave. Ya, does look a little bare.

Posted - 03/13/2017 : 10:47:23 AM Not much underneath, but apparently the prototype didn't have much, either. (Scaled to 30" from the 3' prototype, Tionesta Valley logging RR). No truss rods, and presumably minimal brake rodding for manual brakes only.

Lookin' good Dave. The underside got any detail to it?
Working on a TT scale caboose in brass.
